I don't know what to do anymore!

My grandma runs me down. And she yells at me for stupidest stuff. Like how I didn't turn the T.V off right and how she can't get it back on because I used it last. I'm sick and tired of fighting. I fell like giving up but I cant, I can't because I'm keeping my promise with my cousin that I'd wouldn't give up on my life. Well that was the case tonight, my grandma calls me in and tells me that she can't get the T.V on and I tried explaining in a calm voice that she needs to see if a yellow light is on and if it's not she needs to turn it on. Well she got all up in my case about how I need to turn it off right and how whenever I use it last that it never works. It's getting tiring and I won't even go NEAR to telling her how it's really ticking me off then she'll just complain more and more about things I'm doing. It's ruining me. She starts stuff for the stupidest things. Well she told me that I was a b, it starts with a b and ends with a d. I can't say it cuz I'm under 18 and not allowed to swear. (the rules on here I guess), s.o.b and stuff like that. I told her "and you ask me why I can't wait to move out." and she goes then why don't you go then?

My best friend Mikey and his mother told me that if anything had happened or if I was kicked out that I was able to go move in with them. I'm seriously considering it but then i have to change schools and that. I'm just thinking that maybe I'll just go and try to get a job, maybe odd jobs and save up money and to also pass the time and just not talk to her anymore so I don't get yelled at for stuff (then she'll prolly yell why I don't talk to her) Why can't she be glad that I'm a straight A student, that I'm not doing drugs or going out drinking or smoking, or wearing little tiny skirts waiting on a street corner waiting to be raped and kidnapped or running around with my friends? Why can't she be glad that I'm trying to do something out of my life and be something, be a somebody out of being a nobody?

I don't know what to do,
please help!

P.S- I got alot on my plate now, I'm dealing with my great aunt cancer that will never fully go away. Homework and stuff like that.

Yes I have. And this has been going on for quite a while now.

No its not turning off the T.V for her. It's whenever she turns on the T.V she starts yelling at me because I'm apparently the one that screwed it up last. Its like an automatic -I'm gonna rip out your stupid brains if you dont do it right- kind of yell.

I'm getting sick of it. I don't have to live with someone whos going to keep bringing me down.

I know that its hard ot be optimistic right now. my grandma always yells at me becuase i dont get ready fast enough ( though im always on time) or that i didnt completely clean the house because i had too much homework, or when i do completely clean the house and do my homework later she yells at me for not doing my homework sooner.
my dad does the exact same thing, he used to whip me every day.
my mom says that i hurt her feelings all the time because i dont come to her with stuff, but when i do come to her its like she just shoves my problem away.
my parents have no faith in me and neither do any of my grandparents. my sister and i want to become high school teachers at the same high school and open a restaurant togetther. when i told my dad, he just laughed in my face and my grandmothers think i shouldnt do it because there is no money in it. im not doing it for the money!!!
its really hard to keep your head up since it feels that everyone is trying to drag you down with them, but just know that everything you are going through right now is going to make you so strong in the future. you are going to be able to withstand so much more because of all the things on your shoulders right now. its shaping you into who you will become.
if you believe that you can get through this and withstand it until you are 18, you will be so grateful. you will be able to stand on your own two feet when everyone else is still running to their parents.
i hope that something i said helped, if not then im sorry...
